The DBH 9728Pol is a radial shaft seal that keeps lubricant in and contaminants out of rotating equipment. It fits a 50 mm shaft, a 72 mm housing bore and has a 10 mm overall width, with the Lz-R-AH profile. MR Industrial Accessories supplies this seal as part of its seals and oil seals line for industrial maintenance and repair.

This seal carries the DBH brand and the code 9728Pol. Its three key dimensions are shaft 50 mm, housing 72 mm and width 10 mm. The Lz-R-AH designation describes the lip and body geometry, including the reinforcement. The narrow cross-section suits housings where axial space is tight but a dependable seal is still required.

You will find seals of this size in gearboxes, speed reducers, centrifugal pumps, electric motors, rollers and other power transmission assemblies. The job is always the same: hold oil or grease inside and block dust, water or particles from getting in. It also works as a barrier in dusty or moderately humid conditions, provided the lip contacts the shaft evenly.

Before installing, inspect the shaft for burrs, scratches or wear at the contact area; a rough shaft can destroy the lip quickly. Coat the lip with the same lubricant used in the equipment, then press the seal in squarely, keeping it perpendicular to the shaft and avoiding uneven blows. If the housing has a shoulder or radius, confirm the seal seats completely. Selection depends on lubricant type, speed and operating temperature.

To request a quote for the 9728Pol, send us the code along with the shaft, housing and width dimensions, plus a photo or sketch of the housing. We will review options within the same radial shaft seal category and confirm which one fits without re-machining. If you are unsure about the Lz-R-AH profile, we can check it against the manufacturer's data sheet.
